growing in Kekkila B1W

greetings green-thumbed stoners :)
today i purchased a bale of kekkila B1W substrste... unfortunately i couldnt find the unfertilized kind :( but from what i read its supposed to have an acceptable ph, dolomte lime (which is great since i can only buy hydrated lime) , mycoryza and wetting agent .
its the best thing i could find compared to miracle grow, scotts and shitty local peat.

i also bought a bag of perlite , 5-2.5-2.5 fermented manure ( unknown type) and bloom boost miraclegro.
i'll take clones from unsexed mother plants and grow in a 2sq meter greenhouse (still under construction).
i was wondering if someone had experiance wih kekila's peat and maybe - hopefully some tips and advices regarding nutes and soil mix.
thnks in advance :D
this is my 2nd outdoor grow BTW :)
